We've been buying another brand of mayonnaise, but we may switch to Kraft for the convenience of the Big Mouth jar.**
We love this new packaging. It's easy to hold, lightweight, and easy to use. Kraft even put a flat spot inside the opening for scraping extra mayo off the knife when you're ready to close up. Ingenious!
** We could keep buying the other brand, then wash and fill the nifty jar. The taste difference is negligible. I expect we'll balance price vs. convenience.
